Description

A kind of lead acid accumulator

Technical field

The utility model relates to the storage battery field, specifically refers to a kind of lead acid accumulator.

Background technology

A lot of lead acid accumulators are when design, can adopt lead terminal, and earlier with after lead terminal and the bus-bar welding, go into groove and close the lid, lead terminal sets gradually the lead cover into wedge, cylinder, band mount pad from the bottom to top, and this structure still can not prevent the terminal distortion effectively, if terminal distortion then can make and make resistance become big easily, can influence the sealing effectiveness between terminal and the battery cover, thereby electrolyte leakage can occur, influence the normal use of storage battery.

The utility model content

The purpose of this utility model is to provide a kind of lead acid accumulator that can effectively prevent the terminal distortion.

To achieve these goals, the utility model has adopted following technical scheme:

A kind of lead acid accumulator, comprise battery body, middle cover and loam cake, described middle cover places the top of described battery body, and both are adaptive, described loam cake places the top of described middle cover, the two ends, top of described battery body are provided with terminal, an end of described terminal is upright piece, another end is horizontal block, described terminal is provided with a back-up block parallel and contour with described upright piece, described upright piece is connected by contiguous block with described back-up block, this contiguous block places the top of described upright piece and described back-up block, the lower end of described back-up block is connected with described horizontal block, and the horizontally extending direction of this horizontal block is opposite with the direction of described contiguous block, described upright piece, be equipped with circular hole on horizontal block and the contiguous block;

The top of described middle cover is provided with a boss that is " protruding " shape, the both sides of this boss are respectively equipped with the through hole of the contiguous block that holds described terminal, described boss is provided with liquid injection hole, pole hole and polar biased post hole, described polar biased post hole is two parallel row and places on the described boss, and described liquid injection hole places between the described two row polar biased post holes; Wherein delegation described polar biased post hole and two pole holes are in the same side, and the position in pole hole is corresponding with through hole on the described horizontal block;

Described loam cake is " protruding " shape, and suitable with described boss.

Further, with described pole hole in the distance of the polar biased post hole of the same side and the described liquid injection hole distance greater than another row polar biased post hole and described liquid injection hole.

Further, the shoulder of described loam cake is provided with two buckling partss, and two buckling partss run vertically down, and respectively along the projection left-right symmetric of described loam cake.

Further, described terminal is copper tip.

The utility model is by changing the structure of terminal, the pole hole is by the covering of loam cake, avoided terminal to contact with sulfuric acid and corrodes, and also avoided the distortion of terminal, this terminal structure can satisfy multiple wiring demand, replace plumbous material with copper material, improve product specification, the wiring and the function of use that do not hinder primary cell, when mounted, earlier utmost point group is gone into groove, loam cake covers battery body, after copper tip is connected with lead terminal post with electric iron.
